With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry. 
 
An Italian variant of Cosimo or Cosmas, the name Cosmo has its roots in Greek, where it means "order, universe, beauty." It was first introduced to Britain when an 18th century Scottish Duke used it for his son, in honor of his friend, Cosimo III de' Medici. 
 
Long neglected as it has been in the US, some parents are coming round to the idea of Cosmo again, with nearly 100 boys receiving the name in a recent year. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, while YouTubers Life with Beans used it in 2020, which may well help to change how people view Cosmo. 
 In literature, Baron Cosmo Bradwardine is a character in Sir Walter Scott's novel Waverley and Cosmo Topper is the befuddled banker in Thorne Smith's humorous novel Topper. In modern times Cosmo has become the short form for Cosmopolitan – both the magazine and the cocktail. And for those wishing to honor a medic in the family, Cosmo is also the name of the Arabian-born patron saint of doctors.
 
With its cosmic meaning and creative feel, Cosmo may also appeal to those looking for alternatives to Atlas, or for those who like Evren.
